Security
1x data transmissions are highly secure. Originally developed based upon the
"spread spectrum" pioneered by the US Department of Defense, security in
CDMA technologies is obtained by spreading the digital information contained in
a particular signal of interest over multiple coded paths, over a much greater
bandwidth than the original signal.
Connection methods
You can connect the Raven X to a USB or a Ethernet (RJ45) on a computer.
When connected to a USB or Ethernet port, the Raven X behaves like a network
card.
USB
The Raven X is equipped with a USB port which increases the methods by which
you can send and receive data. The USB port can be set to work as either a
virtual Ethernet port or a virtual serial port. A driver installation is required to use
the USB port in either mode.
It is recommended that you use a USB 2.0 cable with your Raven X and connect
directly to your computer for best throughput.
Virtual serial port
The Raven X supports one virtual serial port over USB. This VSP can be used,
for example, to send AT commands, or to run many serial based applications
®
such as HyperTerminal
Networking
IPSec
The IP protocol that drives the Internet is inherently insecure. Internet Protocol
Security (IPSec), which is a standards-based protocol, secures communications
of IP packets over public networks.
IPSec is a common network layer security control and is used to create a virtual
private network (VPN).
The advantages of the IPSec feature includes:
•
Data Protection: Data Content Confidentiality allows users to protect their
data from any unauthorized view, because the data is encrypted (encryption
algorithms are used).
